General Tsuwabuki commanded the Trained Bands of Amber City under Nanami for decades, and was recently appointed to the position of Marshal, the first non-family member to hold the post.
He has been Nanami's lover for some seventy years now; their relationship is quite public, although some tongues wag about why they haven't gotten married. They have a son, Ramon.
Of late, he has come under repeated assassination attempts by the Bloc Rebmaquois. The reasons behind this are not yet clear.
